SEND International began as Far Eastern Gospel Crusade (FEGC) shortly after World War II by a group of men and women who returned from military service burdened for the spiritual needs of Asia. The early years of FEGC were marked by rapid growth and expansion into new areas. In 1971, Central Alaskan Mission, with its multi-faceted ministries in Alaska, merged with FEGC. In 1981, FEGC became SEND International to better represent the geographic scope of the mission. In 1985, Spain opened up as the next country. At the end of the cold war in the early 1990s, SEND expanded into Central and Eastern Europe. Today, there are approximately 500 SEND missionaries serving in more than twenty countries of Europe, Asia, and North America.

Vince Joy, founder of the Central Alaskan Mission, felt there was a need to reach people living in the bush areas of Alaska and the best way to do this was through radio. This original idea has developed into the Northern Light Network, a subsidiary of SEND International of Alaska, consisting of 2 AM broadcast stations (KCAM, Glennallen and KRSA, Petersburg) and 3 translators from KRSA (in Haines, Sitka and Wrangell).

Early in the morning of March 27, 1964 the engineers gave the final check and announced that KCAM was ready to begin broadcasting. Twelve hours later the great Alaska earthquake struck. The station went on the air with emergency power under special authority to aid rescue and restoration efforts during the five-day crisis. Regular authority for full time broadcasting was granted on April 16, 1964.

Due to inquiries from people in Southeast Alaska, who also wanted a Christian radio station, the mission conducted several survey trips and as a result KRSA signed on the air September 25, 1982. KRSA serves the island community of Petersburg, the waterways around Petersburg, and by translator, the communities of Haines, Sitka and Wrangell.
